Astronomy Wavelength Calculator

Here is the calculator to find the wavelength (λ) from the given frequency of a wave (i.e) the distance it requires to complete one oscillation. In astronomy, λ of a given spectral line is the wavelength of a sine wave. The wavelength astronomy is a branch of astrophysics, learning about astronomical objects and the effects of electromagnetic radiations upon them. In the below astronomy wavelength calculator, enter the frequency to know λ.
